Yes I was referring to a sealed corner enclosure. If you still want to go that route I think you can get it to be very loud but you will need a special sub (I only found one in my search) and you will need at least 800w, better 1000 or more. At that point I do not know if the electrical system is adequate anymore, that's why I decided to go IB.

I decided quite a while ago (2 months) that I want an IB application. Was just intersted in how you found the 2 different applications.
